Answer:

Hey boss man, just add up all the sides! For example, just add 3.9+3.9+3.9! and if there is a line in the middle of a certain side, it means that it is congruent or the same as another side with a dash. For example, with number 2, the side without a measurement is congruent with the the side with measurement of 7mm! Hope this helps! You got this! :)

Step-by-step explanation:

Area is length x width

28=7n where n is the unknown width

Solve for n and u get 4

Answer:

4 metres

Step-by-step explanation:

The garden is in the form of a rectangle. The area of a rectangle is denoted by A = lw, where l is the length and w is the width.

Here, we're given the length is l = 7 and the area is A = 28, so we can plug these into the formula:

A = lw

28 = 7 * w

Divide both sides by 7:

w = 28 / 7 = 4

Thus, the width is 4 metres.

Hello!

In statistics, the relative frequency is the percentage/ proportion of times a determined event has occurred in a given experiment.

In this exercise you have to calculate the relative frequencies of the observed student's behavior, given that they received positive phone calls as an incentive and the observed student's behavior, given that they didn't receive positive phone calls as an incentive.

If "x" represent the number of observations for the category (Desirable behavior and Undesirable behavior) of interest and "n" the total number of observations in each row (Phone call and No phone call), you can calculate the relative frequencies as: f(x)= x/n

For the students that received the phone call:

n= 19 + 9= 28

The student showed desirable behavior: f(x)= 19 / 28= 0.678= 0.68

The student showed undesirable behavior: f(x)= 9 / 28= 0.678= 0.32

For the students that didn't receive the phone call:

n= 8 + 6= 14

The student showed desirable behavior: f(x)= 8 / 14= 0.678= 0.57

The student showed undesirable behavior: f(x)= 6 / 14= 0.678= 0.428= 0.43

Answer:

Answer:

Daniel office is located 20 miles from his house and it took Daniel 25 minutes to drive that distance.

Step-by-step explanation:

Since the graph shows the distance from his house to his office as a function of driving time, then when the driving time is equal to "0", it means that he didn't left his house yet and that is the distance from his house to his office. On the graph this is the point that crosses the "y" axis, 20 miles. When he arrives at his office, then the distance is equal to "0", since he already arrived at his destination. This happens when the graph crosses the "x" axis, which happens on the 25 min mark. So:

Daniel office is located 20 miles from his house and it took Daniel 25 minutes to drive that distance.

Hello!

[tex]\boxed{ \bf The~area~of~the~shaded~region~is~B.~24 mm^2}[/tex]

______________________________________________________

To find the area of the shaded region, we must find the area of the inner white triangle and subtract it from the area of the outer blue one.

Outer:

A = [tex]\frac{1}{2}[/tex]bh

A =  [tex]\frac{1}{2}[/tex](12 · 5)

A =  [tex]\frac{1}{2}[/tex](60)

A = 30 mm²

Inner:

A = [tex]\frac{1}{2}[/tex]bh

A = [tex]\frac{1}{2}[/tex](4 · 3)

A = [tex]\frac{1}{2}[/tex](12)

A = 6

30 - 6 = 24

Answer:

The slope would be 7/5

Step-by-step explanation:

The slope is 7/5 because you can calculate slope by dividing the change in the y-value between two points over the change in the x-value. (y-y/x-x) you would just plug in the the points for X and Y, 5-(-2)/3-(-2) and you would get 7/5.

Answer:

+6 and -6.

Step-by-step explanation:

x = +/- 6.

The two values which x can have will be +6 and -6

What is Quadratic Equation?

A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c =0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.

Given data ,

Let the equation be f ( x )

The equation f ( x ) is x² - 10 = 26

Now , adding 10 on both sides , we get

x² = 36

Taking square roots on both sides , we get

x = ±6

We know , (-6)² = 36 and (+6)² = 36

Therefore , x can have 2 solutions , which is ±6

Hence ,  the two values which x can have will be +6 and -6
